It's not that Nothing is Sacred, it's that what used to be sacred is So Very Yesterday, and what is now sacred is, well, Verizon and iPhones and desire for Shiny Electronic Stuff that is so strong that we get hit over the head with commercials like this.
So a bunch of strangers show up to sing about the latest stupid toy the already over-indulged Child Living in an Adult's Body wants because it happens to be the Christmas season, as if the Season for Giving Yourself Things isn't all year round these days.
And the people answering the door just take this in stride. As do the people in the comment section. That is, when they aren't asking for the lyrics to the "song" or wondering who the "actors" in this thing are. Gross.
